I picked up my can over the weekend so I rolled up some subs to try out tonight.
Gun: 300blk SBR 9inch barrel using a Vortex AR red dot
load
220gr leatherhead bullets
COL- 2.065
A1680
made some in .2 increments from 10.4- 11.4gr
My gun really seemed to like 10.8gr
Mind you this was at an indoor range shooting 25yds and I don't own a chrono.
But , they were quiet
Just curious who else is rolling up 300blk subs and what you are using.
If anyone has a chrono I would love to meet up and shoot.
I have no idea on fps on these.
